In addition to relations with the Soviet Union, Vietnam maintained close relations with other members of Comecon and the Warsaw Pact. Eastern Europe provided Vietnam with some US$844 million in aid between 1965 and 1975, amounting to 18 percent of all aid received during that period. Between November 1976 and June 1977, Vietnam signed commodity and payments agreements with eight communist countries, cultural agreements with four, scientific cooperation agreements with eight, and separate agreements for economic, scientific, or technical cooperation with five. Its relations with Czechoslovakia, the German Democratic Republic (East Germany), and Hungary were particularly close.
